Florida-based, ICM Registry, the official registry for the new .XXX top-level domain, is using a curious marketing tactic to spread the word about its global availability, which starts December 6, 2011. It has sponsored the Race of Champions at Duesseldorf's ESPRIT arena this weekend. Here's the Palm Beach company's press release.

"We are very excited about sponsoring this world class auto racing event," said Stuart Lawley, CEO of ICM Registry. "We are putting our full support behind promoting .XXX as a global brand and sponsorships of events like this bring a new level of awareness to consumers about the domain."

The Race of Champions will feature some of the leading names in motor sport including current Formula 1 world champion Sebastian Vettel, seven-time title winner Michael Schumacher and F1 world champion Jenson Button.

.XXX branding will be featured around the stadium along with its new video advertising running on large screens, placement in the VIP area and as a host of the post-race party.
